Uh, the last time I checked, Superman was based in a town called “Metropolis.” BATman made his home in Gotham City. And The Incredibles are evidently based in “Metroville”

And of course, Captain Amazing was the resident superhero in Champion City, until his accidental “friendly fire” demise at the hands of his would-be rescuers, the Mystery Men. I don’t think a specific location was ever given for Batfink, Underdog, or Super-Goof.
